Face to face interviews were conducted using socio-demographic performa, Malay version Geriatric Depression Scale 14 (M-GDS 14), Malay version Trauma Screening Questionnaire (TSQ) and flood-related questionnaires. Results: One hundred elderly respondents completed the study. The prevalence of depression and traumatic stress was 15.0% and 17.8%, respectively. The risk factors for depression are being female (Odds ratio [OR] = 5, 95% Confidence Interval [CI]: 1.27, 19.99), family history of mental illness (OR = 39.5, 95% CI: 1.41, 1063.08) and elderly with traumatic stress (OR= 5.38, 95% CI: 1.53, 18.9). There was significant correlation between depression and traumatic stress (r= 0.36, p<0.001). Conclusion: In the aftermath of a natural disaster, female and those who have PTSC are more likely to develop depression.
